Question

How many neutrons are present in 180 ml water at 127° Celsius and 0.831 ATM pressure?​

Answer 1

Since m=ρ×V,

m=18 g

Hence number of molecules of H2O=1×6.022×10 23

Number of moles=

18

18

=1

Number of neutrons present in a molecule of H2O=2+6=8

Number of neutrons present in 6.022×10  23

molecules of 8×6.022×10  23

=4.8176×10  24
